Select2 4.0.0 Bootstrap theme

Asked 30/3, 2015 at 23:9 Answered 26/5, 2021 at 20:59

In select2 4.0 version there is a theme option. However in the documentation I can't find what does the option mean and how can I create custom theme (https://select2.github.io/examples.html)

I've found bootstrap 3 theme for select2, but it seems to be working only for 3.5 version.

So I could I create custom theme for select2 latest version (4.0)? Basically I need bootstrap 3 styling preferably with LESS file

@fk is working on a Bootstrap 3 theme for Select2 4.0.0.

There is not currently any documentation on creating themes for Select2 4.0.0, but it may help to look at the default theme's SCSS for the selectors.

Okay, thanks. Actually I've chosen another plugin since I got some troubles with this one (if I remember correctly adaptive design problems). But anyway, thanks – Indulge 6/4, 2015 at 10:7

@Indulge Which plugin did you end up going with? – Korfonta 7/9, 2019 at 4:17

If you want to use bootstrap styling from Kevin Brown' answer

https://github.com/select2/select2-bootstrap-theme

You add this css file to your page, keep the default select2 styles

<link href="/select2-bootstrap-theme/select2-bootstrap.min.css" type="text/css" rel="stylesheet" />

Then set the theme

$("#elem").select2({theme:"bootstrap"});

Also, use classes .select2-bootstrap-prepend and .select2-bootstrap-append on the .input-group wrapper elements to group buttons and selects seamlessly.
